The utility model discloses an aim at providing one kind rational in infrastructure, convenient to use, simultaneously mineral insulated cable with strong resistance to compression function in the use.
Description
Technical field
This utility model belongs to technical field of electric wires and cables, espespecially a kind of cable, is specifically related to a kind of mineral insulated cable with stronger resistance to compression function.
Background technology
Fast development along with society, various electrical equipment have also been obtained effective development, and connect one important accessory of electrical equipment of cable effect, have also been obtained effective development, the cable of prior art is mainly made up of restrictive coating, conductor and flame retardant coating, although it can realize conducting function to a certain extent, but the cable stability in use of prior art is poor, and shield effectiveness inconspicuous, have impact on the suitability of cable to a certain extent.
At present, in prior art, the sheath great majority of cable are to use plastics and rubber organic polymer composition; it is typically all one layer, when using in certain environments, inadequate to the protection of cable core; especially by extraneous pressure, easy damaged cable core, affect the normal use of cable.
Utility model content
For above-mentioned weak point of the prior art, the purpose of this utility model is intended to provide a kind of rational in infrastructure, easy to use, in use has the mineral insulated cable of stronger resistance to compression function simultaneously.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions:
A kind of mineral insulated cable with stronger resistance to compression function, including overcoat and inner core, described overcoat and inner core are arranged concentrically and inner core is positioned at jacket internal；Described inner core outer rim is provided with insulating barrier, and described inner core is to be formed by the soft round copper wire layering strand system that some diameters are identical；Described overcoat uses double-decker to arrange, and described jacket internal is provided with some flexible adjustment keys, is provided with gripper shoe and packed layer between described insulating barrier and overcoat.
Further preferably, described gripper shoe and packed layer is circumferentially staggered is arranged between insulating barrier and overcoat, described packed layer is mineral-filled layer.
Specifically, inner core is that layering strand system well-regulated by the soft round copper wire that some diameters are identical, concentric type forms；Insulating barrier is arranged at outside inner core, it is possible to effectively prevent inner core from electric leakage occur；Flexible adjustment key coordinates gripper shoe can effectively reduce cable entirety stress thus improves cable service life, finally, in the case of reducing cost, do not reduce cable entire compression because packed layer is mineral-filled layer, the most also there is certain solar heat protection function, extend cable service life.
Further preferably, described overcoat is butyronitrile oversheath, and it has stronger anti-corrosion effects.
Further preferably, described gripper shoe is triangular support plate and arranges relative to inner core circular array.
Further preferably, described flexible adjustment key is compression spring and arranges relative to inner core circular array, and flexible adjustment key is arranged at below flexible adjustment key axis than for 1:1 and described gripper shoe with gripper shoe quantity.
This utility model has the advantage that relative to prior art
This utility model in use, has stronger crushing resistance, and service life is longer；Therefore, in sum, this utility model has stronger operability, it is simple to be widely popularized universal use.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment, the accompanying drawing used required in embodiment will be done simple introduction below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art under not making creative work premise, the every other embodiment obtained, broadly fall into this utility model protection domain.
A kind of mineral insulated cable with stronger resistance to compression function as shown in Figure 1, including overcoat 1 and inner core 2, described overcoat 1 is arranged concentrically with inner core 2 and inner core 2 is positioned at jacket internal；Described inner core 2 outer rim is provided with insulating barrier 3, and described inner core 2 is to be formed by the soft round copper wire layering strand system that some diameters are identical；Described overcoat 1 uses double-decker to arrange, and described overcoat 1 is internally provided with some flexible adjustment keys 5, is provided with gripper shoe 6 and packed layer 4 between described insulating barrier 3 and overcoat 1.
Further preferably, described gripper shoe 6 and packed layer 4 is circumferentially staggered is arranged between insulating barrier 3 and overcoat 1, described packed layer 4 is mineral-filled layer.
Specifically, inner core 2 is that layering strand system well-regulated by the soft round copper wire that some diameters are identical, concentric type forms；It is outside that insulating barrier 3 is arranged at inner core 2, it is possible to effectively prevents inner core from electric leakage occur；Flexible adjustment key 5 coordinates gripper shoe 6 can effectively reduce cable entirety stress thus improves cable service life, finally, owing to packed layer 4 does not reduce cable entire compression for mineral-filled layer in the case of reducing cost, the most also there is certain solar heat protection function, extend cable service life.
Further preferably, described overcoat is butyronitrile oversheath, and it has stronger anti-corrosion effects.
Described gripper shoe 6 is triangular support plate and arranges relative to inner core 2 circular array.
Described flexible adjustment key 5 is compression spring and arranges relative to inner core 2 circular array, and flexible adjustment key 5 is arranged at below flexible adjustment key 5 axis than for 1:1 and described gripper shoe 6 with gripper shoe 6 quantity.
